Make sure to read the description carefully all the way to the bottom. The host introduces additional costs which drastically impacts the affordability of the rental. Charged an extra 3000 baht for electric/water for just 5 days. (Definitely greater than the cost to the host) Threatened with a 2000 baht charge for having 2 friends come in and visit one evening.
I told the host to send me the bill on checkout and I would do a direct bank transfer for whatever costs she wanted me to pay. On a particularly busy morning trying to catch a flight on my way out, the host had security physically restrain my bags until she could physically see me perform the bank transfer in front of her (as a result nearly missed my flight).
I've stayed in dozens of airbnbs all over Bangkok and never been surcharged or inconvenienced like this. I'd recommend booking elsewhere.
